Computer simulations have revealed how the electrical conductivity of many materials increases with a strong electrical field in a universal way. This development could have significant implications for practical systems ...

Physicists at the University of Michigan say they have devised a more elegant way to fine-tune the behavior of topological insulators—peculiar, two-faced materials whose electrical properties differ markedly between their ...

Researchers from MESA+, the research institute for nanotechnology at the University of Twente, have developed a method to reduce the number of 'defects' in heterogeneous oxide materials. As a result, the electrical conductivity ...
